ARNOLD CLARK, 0F LATTY, OHIO.

RAILWAY-TIE.

To all whom it may concern:

Be it known that I, ARNOLD CLARK, a citizen of the United States, residing at Latty, in the county of Paulding and State of Ohio, have invented a new and useful Railway- Tie, of which the following is a specification.

This invention relates to railway ties and one of its objects is to provide a composite device of this character having a base of plastic material above which is yieldingly supported a metallic cap designed to engage the rails of the track.

A further object is to provide improved means for holding the cap and body properly assembled.

Another object is to provide a cap including integral means for engaging the rails thereof.

A further object is to provide novel means cotiperating with the cap for the purpose of securing the rails in place.

\Vith these and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :Figure 1 is a view partly in elevation and partly in section of a tie constructed in accordance with the present invention. Fig. 2 is a section on line A..-B Fig. 1. Fig. 3 is a section on line (l-D Fig. 1.

Referring to the figures by characters of reference 1 designates the body of the tie, the same being formed of concrete, which may, if desired, be suitably reinforced. This body ha a central recess 2 in the upper face thereof and additional recesses 3 are formed in said upper face adjacent the ends of the body. Each of the recesses 3 has a metallic lining at surrounding a coiled cushioning spring 5 which is in turn disposed about a tubular guard (3 formed of metal and in which is arranged another smaller supplemental coiled spring 7. The tubes (3 and the lining 1 have their upper ends flush with the upper surface of the body 1 but the two springs 5 and 7 project above the body for the purpose hereinafter set forth. The cap of the tie is preferably formed in a single piece of metal and has flanges extending downwardly from the Specification of Letters Patent.

edges thereof. This cap has been designated Patented Oct. 18, 1910.

Serial No. 567,313.

generally by the numeral 8 and the flanges have been indicated at 9. The recess 10 formed by the flanges 9 is of such size as to receive the upper portion of the body 1 and a stem 11 is formed upon the center ofthe bottom of the cap and is adapted to project into the recess 9. and to slide and rotate therein. Additional stems 12 project downwardly from the cap at points adjacent its ends and are adapted to project into the springs 7, the upper ends of these springs and the springs 5 bearing upwardly against the cap 8 so as to yieldingly support it.

Transversely extending shoulders 13 are formed upon the cap 8 adjacent its ends, each of these shoulders being under-cut as shown so as to lap one of the base flanges of a rail 14. A fastening plate 15 is interposed between and spaced from the shoulders and has its ends under-cut as indicated at 16 so as to lap the inner base flanges of the rails 14. This plate 15 may be secured to the cap 8 in any suitable manner, as by means of bolts 17 extending through the cap and through the plate.

It is to be understood that the rails let are secured to the tie by placing their outer base flanges in engagement with the shoulder 13, after which the plate 15 is secured in engagement with the inner base flanges of the rails. Before the rails are fastened in this manner, the cap 8 is placed upon the body 1 and with the stem 11 projecting into recess 2 and the stems 12 projecting into the recesses 3. Springs 5 and 7 bear upwardly against the cap and thus serve to yieldingly support the lower face thereof outof contact with the body 1. The flanges 9, however, constantly close this space so as to prevent the admission of dirt or moisture thereto.

When the tie is subjected to the weight of a car passing thereover, the cap 8 will be pressed downwardly so as to place the springs under stress. It Will thus be seen that the tie, although formed of concrete and metal, will be sutliciently resilient to overcome the objections incident to the use of rigid concrete or metal ties such as heretofore devised. By utilizing two coiled springs in each recess, the resistance to the downward movement of the cap 8 is increased when the load exceeds a predetermined limit, this being due. to the fact that the supplemental springs are then brought into play.

It Will be apparent that various changes may be made in the construction and arrangement of the parts Without departing from the spirit or sacrificing any of the advantages of the invention as defined in the appended claims.

lVhat is claimed is l. A railway tie including a plastic body having recesses in its upper face, a cap extending continuously throughout the length and width of the body, an extension upon the cap and slidably mounted within one of the recesses, non-contacting nested cushioning devices within the remaining recesses and bearing upwardly against the cap to hold it outof cont-act with the body.

2. A railway tie including a plastic body having recesses in its upper face, metallic linings within certain of the recesses, outer and inner concentric springs within the lined recesses, a cap, stems projecting therefrom and into the recesses, said springs constituting means for holding the cap normally spaced from the body, and flanges depending from the cap and closing the space between the cap and body.

3. A railway tie including a body, a spring supported cap spaced therefrom, means upon the cap for closing the space between the cap and body, said cap having rail engaging shoulders, a rail securing plate interposed between the shoulders, and means for fastening said plate to the cap.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence 0]": two witnesses.
